1. Warm Up Graph the following functions on the same coordinate plane:

2. Answers Graph the following functions on the same coordinate plane:

4. Piecewise Functions Piecewise functions are neighbors! Their properties are separated by a fence.

5. Example 1 1 1 2 2 It’s in two pieces! Each piece must live ONLY in its own neighborhood. Let’s put up a fence, so we don’t make any mistakes! These number(s) tell us where to put a fence.

6. Example 1 These number(s) tell us where to put a fence. lives here Now, we need to figure out who the fence owner is. This guy has the “=”, so he gets to sit ON the fence. 1 1 2 2

7. Example 1 Let’s graph part 1. This guy has the “=”, so he gets to sit ON the fence. 1 1 2 2 He does not get to sit on the fence.

8. Example 1 This guy has the “=”, so he gets to sit ON the fence. 1 1 2 2 Let’s graph part 2. Since he owns the fence, he can sit on it.
